vocabulary: - term: trace definition: >- A recorded execution of an LLM call or chain of calls, capturing inputs, outputs, latency, token usage, cost, and metadata for observability. - term: trace_log definition: >- The stored artifact representing a single trace, including model configuration, messages, scores, and evaluation results. - term: experiment definition: >- A structured run of a test suite against a dataset using specific prompt versions or model configurations, producing aggregate statistics. - term: dataset definition: >- A named collection of test cases used to evaluate LLM application performance across different prompt or model versions. - term: test_case definition: >- A single input/output pair or scenario within a dataset, used to benchmark and evaluate LLM responses. - term: completion definition: >- A request to the Parea LLM proxy gateway to generate a model response, with built-in caching, retries, and observability. - term: feedback definition: >- Human or automated evaluation attached to a trace, recording scores and labels that measure output quality. - term: project definition: >- A top-level organizational unit in Parea grouping related traces, experiments, and datasets. - term: prompt_version definition: >- A specific version of a prompt template stored in Parea, enabling reproducible experiments and A/B testing. - term: annotation_queue definition: >- A queue of trace logs assigned for human review and labeling to collect ground-truth feedback data. - term: evaluation definition: >- The process of assessing LLM output quality using automated metrics, human feedback, or LLM-as-judge techniques. - term: score definition: >- A numeric or categorical measurement of LLM output quality on a particular evaluation dimension, attached to a trace or experiment row. - term: x_api_key definition: >- The API authentication header used to authenticate requests to the Parea REST API, generated from the Parea settings page. - term: llm_proxy definition: >- The Parea gateway that unifies access to multiple LLM providers with built-in caching, retries, and automatic trace logging. - term: latency definition: >- The elapsed time in seconds between sending an LLM request and receiving the full response, tracked per trace.
